Risk factors

By Mayo Clinic staff

Children are much more likely to develop intussusception than adults are. It's the most common cause of bowel obstruction in children between the ages of 3 months and 6 years, with the majority of cases occurring among children younger than 1 year. Intussusception affects boys twice as often as girls. Malrotation, a condition present at birth (congenital) in which the intestine doesn't develop correctly, also is a risk factor for intussusception. Once you've had intussusception, you're at increased risk to develop it again.
